The United States is sending about 2,000 troops to help Israel.
According to officials, the troops will not serve in a combat role but would be tasked with medical support or advisory duties.
This comes after the Department of Defense said the USS Dwight D. Eisenhower strike group, which deployed from Norfolk, Virginia, on Friday, is on its way.
She will join the USS Gerald R. Ford, which arrived off the coast of Israel last week.
The presence of two of the Navy's most powerful warships will send a clear signal to Iran and its regional proxies, such as Hezbollah, not to escalate the conflict.
It comes as Israel continues to mass troops and military hardware around the Gaza Strip, from where Hamas gunmen launched a surprise assault on Israel, killing at least 1,300 people.
Officials cited by the Wall Street Journal also said some 2,000 troops were being prepared to deploy in a sign that Washington was ready to assist Israeli troops in the event of a ground invasion of Gaza.
Western leaders have lined up to urge Israel to follow international law and not trigger a wider regional conflagration.
Iran told Israel via the United Nations it would intervene if operations in Gaza continued, a report claimed, as Israel readied a 'wide range of offensive operational plans' including a 'joint and coordinated attack [on Gaza] from the air, sea, and land.'
Diplomatic sources told Axios that while Iran did not want the conflict to escalate, it was prepared to intervene either directly or indirectly, such as via a military group in Syria or Lebanon.
Schools in Lebanon remain closed amid fears of Israeli missiles targeting Hezbollah militants near the border. While Hezbollah has not formally joined the war, the group has clashed with Israeli forces several times this week.
Israel has called up 360,000 reservists as it prepares for its next move.
